AA upper & barrel ?

[Blacklab]

Hey guys I just orderd a barrel an upper from AA about a week ago. I was just wondering if they were put together, or do they come in parts. To late to call an ask, an to excited to wait...............lol

Thanks.

If just two parts, an upper receiver and a barrel, they will not be assembled. Assembly would require a barrel nut, which varies according to handguard.

If a complete upper, it would be assembled and ready to pin to a lower.
